In 2010, he attended Sol del Rió and Leopoldo Estol’s "Encuentros de Dialogos Con Artistas" at Bruzzone Museum.

Trying to avoid the usual, Jose Maria has developed a strong personal style that outstands for its shocking but clear use of color, the balance and equilibrium of his compositions which creates the feeling that "everything is in it's right place", and his painting's great expressionism. His approach to the art materials is goes trougth the experimental path, and his creations are strongly influenced by music.

His work plays with the multiplicity of interpretations. He wants it, he goes for it. Instead of closing and imposing, his work tries to open and liberate, so as to trigger thoughts and imagination. For this purpose the author, throughout his process on material experimentation and composition, has tried to crush shape, freeing both color and audience from structure. When there is, or seems to be, structure in his work, it has been purposely faked, as a game that tries to seduce the eyes for a few seconds, triggering an acknowledgment and identification attempt, which later vanishes to leave the painting, once again, on the grounds of multiple interpretations. This search guided Casas to experiment with different mediums, which allow him to break not only shapes but also the plane.

His work can be found at private collections in Argentina, Chile, Spain, United States, Honduras, England, Mexico, Panama, and Thailand; at public collections in Argentina, Honduras, Italy and Mexico; and at Galleries in Argentina, United States, Italy and Turkey.
